Place the asparagus on a rimmed baking sheet. Drizzle with the oil
and shake the pan to coat the asparagus. Season with the salt and
pepper. Roast, shaking the pan occasionally, until the asparagus are
tender, 7 to 10 minutes (depending on the thickness). Remove from oven.

Heat broiler on high. Sprinkle the Parmesan over the
asparagus. Broil until crisp and golden, 2 to 3 minutes. Serve
immediately.
